Screw parameters not matching the material affect processing quality
Sorun Belirtisi
Screw parameters not matching the material affect processing quality
Neden Analizi
Screw compression ratio too large, excessive shear, degradation
Screw L/D ratio improper, insufficient plasticization
Screw head design improper, uneven mixing
Screw material not suitable for cellulose acetate butyrate, fast wear
Screw does not match the melting characteristics of cellulose acetate butyrate
Çözüm
Select a screw compression ratio suitable for cellulose acetate butyrate (2.5-3.0)
L/D ratio 20-25:1 is generally applicable
Optimize the screw head design
Select wear-resistant screw material
Select the screw according to the melting characteristics of cellulose acetate butyrate
Temel Çıkarım
The screw needs to match the material melting characteristics
